WOOD OR THE LIKE TTTORKENG ACCESSORY.

Appflication filed June 19, 1924.

To all whom it concern Be it known that I, Cnarmns B. lilcCsii- LUM, acitizen of the United States, residing at Oakland, in the county ofAlameda and State of California, have invented certain new and usefulImprovements in Wood or the like WVorking Accessories, of which thefollowing is a specification.

My invention relates to an improved wood or the like working accessory,and has for its primary object to provide means whereby nails or thelike may be temporarily but securely driven into a board, block, stripor other such embedding base, and readily ex tracted or withdrawn fromsecurement with the aid of the accessory in a convenient and time-savingmanner.

The several features of the invention will be readily appreciated uponreference to the accompanying sheet of drawings and the followingdetailed description thereof.

In said drawings: Figure 1 is a front elevation of the pulling ordrawing implement, and Fig. 2 is an edge view of the same in sectionalong the line 2-2 of Fig. 1; and Fig. 3 is an end view of the implementof Fig. at is a plan of the shim member of the invention, and Fig. 5 isan edge view of the same in section along the line 5 5 of the saidfigure; and Fig. 6 is an end view of the shim.

Fig. 7 is a horizontal section of a doorway construction showing one useof the accessory in combination with a removable metal ground, and Fig.8 is a vertical face view of the ground of Fig. 7 and illustrates theuse of the shim member of the invention as applied to the said ground.

Fig. 9 is a plan of the shim and the pulling implement; the shim isengaged beneath the head of a nail and the implement member embraces theshimthe first step previous to pushing the shim from engagement with thenail.

Fig. 10 is a similar view of the pulling implement with the shim removedfrom beneath the nail head, and shows the implement beneath the nailhead and substituted for the shim.

Fig. 11 is a view in front elevation of the pulling implement asequipped with a different form of handle.

Referring to the drawings in detail: the number 12 represents the shimmember and which I prefer to stamp or otherwise pro- Serial No. 721,075.

duce from metallic material, so as to derive a relatively thinblock-like piece of a width and thickness suitable for the purpose. Thisshim is provided with an open slot 13 having rabbeted corners 141- and15. The slot 13 is adapted to straddle a nail or the like 16, and therabbeted corners are adapted to cooperate with the projecting taperedstuds 17 and 18 at the corners of the open slot 19 in the pulling orextracting implement 20 for guiding and prying purposes.

The implement 20 is made with a relatively large and squared opening 21,and of a width to receive the shim 12 so that the studs 17 and 18 mayengage the rabbeted corners 1d and 15. and the slot 19 register with theslot 13, Fig. 9, so as to leave a relatively long opening for the nailwhen the parts are placed together.

The two opposite side edges of the shim are beveled, as at 22 and 23,and the two corresponding edges of the opening 21 of the implementmember are likewise beveled to make a fit for guiding and pryingpurposes also.

The important object of the invention is to provide means which may beinserted or placed beneath a nail or the like head, so that the nail maybe driven tightly into a board or the like as a temporary holding means,and thereafter be removed without injury to the wood or support, and theinconvenience of getting a tool under the head such as would be the caseif the nail head i was driven in to contact with the surface of theboard. With my accessory I can simply insert one of these shims undereach nail head, when nearing the final drive, so that the slot 13straddles the nail shank. The nail may then be driven home and the fullsecuring effect of the same realized. and at the same time leaving itreadily pullable by first removing the shim, and the same removingmember adapted to withdraw the nail almost simultaneously.

To remove the shim, the implement is introduced to the shim as bestshown in Fig. 9, so that the studs 17 and 18 engage the corners 1 1 and15, and a portion of the shim is received within and embraced by thesides of the opening 21. This leaves the two slots 13 and 19 in registryrelation, so that athrust or push on the implement member will slide theshim from under the nail head. After the shim has thus been released,the nail is now straddled by the slot 19, Fig. 10, and

the same may be pulled out by pressing down on the handle of theimplement member.

The release of the shim and the nailextracting operation is practicallyone and the same, that is to say the pulling operation is nothing morethan a continuation of the shim releasing act. The entire operation issimply a thrust forward and then a push downward. The handle of theimplement is curved, as bestshown in Fig. 2, to effect the desiredleverage for the pulling step.

For heaving work I would suggest making the pulling implement with astout handle bar as shown in Fig. 11.

The accessory will work to advantage in many different instances, wherenails or the like headed securing means are employed as a temporarymedium for fastening two or more parts together. As an example, I canrefer to Figs. 7 and 8, wherein I have shown the accessory incombination with a metal ground A as used in the plasterers art. In thisparticular case, the ground A must be temporarily fastened to thestudding B of a doorway, to provide for a uniform thickness of plasteredwall G about the doorway. The accessory also finds expression as a mostconvenient device for pattern makers, and in a host of other arts wherethe same fastoning principle is involved.

While I have thus described the preferred form of my invention, I wishto have it understood that changes may be made within the scope of theclaims hereto attached with out affecting the spirit of the invention,therefore, what I claim as new and desire to secure by Letters Patent ofthe United States, is the following:

1. An accessory of the class described, comprising a slotted shim and ajawed and slotted implement having a curved handle, the opposite sidesof the shim and the corresponding sides of the jaws being beveled forguiding purposes, the shim adapted to be engaged beneath the head of anail or the like fastening means with its slot straddling the nail, andthe implement adapted to embrace the shim and by a downward thrustremove the shim and engage its slot under the nail head, and by abackward movement of the handle of the implement withdraw the nail fromservice.

2. In an accessory of the class described, a shim having a slot andadapted to be placed beneath the head, of a nail or the like fasteningmeans and with the nail received in said slot, means for removing saidshim after the nail has been driven into a support comprising animplement having a jawed-opening adapted to embrace the shim and a slotin said opening adapted to register with the in said opening adapted toregister with the H slot in the shim, and a handle for thrusting theimplement against the shim to pushthe same from beneath the head of thenail, the said slot in the implement adapted to straddle the nail afterthe release of the shim and the implement further adapted to withdrawthe nail.

4s. The combination as set forth in claim 3, and in which the corners ofthe shim at opposite sides of the open slot are rabbeted and theimplement provided with studs adapted to engage said rabbeted cornerssubstantially as described.

In testimony whereof I afiix my signature.

CHARLES '13. MoOALLUM.
